Reducing Readmissions Post-tonsillectomy: A Quality Improvement Study on Intravenous Hydration.

INTRODUCTION: Dehydration is a potentially preventable complication post-tonsillectomy and can result in an Emergency Department visit and/or readmission. Our objectives were to identify risk factors for dehydration readmissions and develop interventions to prevent them. METHODS: We used retrospective chart reviews to determine if increased intravenous (IV) hydration post-tonsillectomy prevented hospital readmissions for dehydration. All children aged 1-18 years who underwent tonsillectomy between July 1, 2007 and September 30, 2015 were included in this quality improvement study. Using the Pediatric Health Information System database, patients who experienced a readmission for dehydration within 72 hours of surgery were identified and validated with internal data. We analyzed the pre-implementation and post-implementation readmission rates after standardization of increased IV fluids (1.5 times maintenance). An interrupted time series analysis was used to estimate the effects of our hydration initiative. RESULTS: Of 11,157 patients who underwent tonsillectomy during the study period, 96 (0.9%) met the criteria for readmissions for dehydration. The pre-implementation readmission rate was 1% compared to 0.2% post-implementation, a reduction of 82%. CONCLUSIONS: The hydration initiative was associated with a significant decrease in hospital readmissions. This safe, low-cost, easy-to-implement approach to preventing dehydration post-tonsillectomy could be explored at other institutions.

The Edematous and Erythematous Airway Does Not Denote Pathologic Gastroesophageal Reflux.

OBJECTIVE: To determine if the reflux finding score (RFS), a validated score for airway inflammation, correlates with gastroesophageal reflux measured by multichannel intraluminal impedance (MII) testing, endoscopy, and quality of life scores. STUDY DESIGN: We performed a prospective, cross-sectional cohort study of 77 children with chronic cough undergoing direct laryngoscopy and bronchoscopy, esophagogastroduodenoscopy, and MII testing with pH (pH-MII) between 2006 and 2011. Airway examinations were videotaped and reviewed by 3 blinded otolaryngologists each of whom assigned RFS to the airways. RFS were compared with the results of reflux testing (endoscopy, MII, symptom scores). An intraclass correlation coefficient was calculated for the degree of agreement between otolaryngologists' RFS. Receiver operating characteristic curves were created to determine the sensitivity of the RFS. Spearman correlation was calculated between the RFS and reflux measurements by pH-MII. RESULTS: The mean ± SD RFS was 12 ± 4. There was no correlation between pH-MII variables and mean RFS (|r| < 0.15). The concordance correlation coefficient for RFS between otolaryngologists was low (intraclass correlation coefficient = 0.32). Using pH-metry as a gold standard, the positive predictive value for the RFS was 29%. Using MII as the gold standard, the positive predictive value for the RFS was 40%. There was no difference in the mean RFS in patients with (12 ± 4) and without (12 ± 3) esophagitis (P = .9). There was no correlation between RFS and quality of life scores (|r| < 0.15, P > .3). CONCLUSIONS: The RFS cannot predict pathologic gastroesophageal reflux and an airway examination should not be used as a basis for prescribing gastroesophageal reflux therapies.

Clinical experience in diagnosis and management of superior semicircular canal dehiscence in children.

OBJECTIVES/HYPOTHESIS: To identify clinical characteristics of pediatric superior semicircular canal dehiscence (SSCD) and explore suitable options of management. STUDY DESIGN: Retrospective review. METHODS: The study comprised 10 patients with auditory and/or vestibular symptoms suspicious for SSCD. One patient pursued care at another institution, and two did not return for follow-up. Subsequently, seven patients (11 ears, 6 females and 1 male, aged 5-11 years) were included. Patients were evaluated using high-resolution temporal bone computed tomography. Those suspected of having SSCD underwent vestibular evoked myogenic potential testing for confirmation in addition to routine audiologic tests. RESULTS: All seven patients had auditory and/or vestibular impairment. Auditory symptoms included autophony, tinnitus, and conductive or mixed hearing loss. Bone conduction responses were occasionally better than 0 dB HL. Vestibular dysfunction included vertigo, often in response to loud noises, and chronic disequilibrium. One patient underwent surgical repair for disabling vestibular symptoms with dramatic improvement in both auditory and vestibular symptoms postoperatively. The remaining six were closely monitored with routine exams. CONCLUSIONS: In contrast to adults, children with SSCD usually present with auditory symptoms first, although they share some similarities with adults in clinical manifestations of SSCD. Our study shows that SSCD syndrome, a well-accepted clinical entity, exists in the pediatric population. Conservative management is preferred for children with SSCD; nevertheless, surgical intervention is necessary for those with disabling vestibular symptoms. To date, this is the first clinical case series of symptomatic pediatric patients with SSCD.

Superior semicircular canal dehiscence in a young child: implication of developmental defect.

In recent years, superior semicircular canal dehiscence (SSCD) has been recognized as a structural cause of a number of auditory and vestibular symptoms, such as vertigo and conductive hearing loss. Prior clinical studies on SSCD have commonly described this entity in adults, but rarely in the pediatric population. We present a pediatric patient with right-sided SSCD which was initially diagnosed radiographically at age seven. This rare and unique case demonstrated SSCD can be found in young children, although the majority of patients with SSCD are adults. It also provides strong evidence that canal dehiscence may be a developmental defect.

A comparison of electronystagmography results with posturography findings from the BalanceTrak 500.

OBJECTIVE: To determine a correlation between conventional electronystagmography findings with results obtained from BalanceTrak 500 posturography assessment. STUDY DESIGN: Individuals with a variety of dizziness and balance disorder symptoms were tested with both electronystagmography (ocular motor studies, positional/positioning testing, caloric testing) and computer posturography using the BalanceTrak 500. SETTING: Tertiary referral center. PATIENTS: Urban/rural midwesterners referred for dizziness and balance dysfunction symptoms. INTERVENTION: Results of both testing modalities were sent to referring physicians. OUTCOME MEASURES: Electronystagmography and posturography results. RESULTS: When electronystagmography results were compared with BalanceTrak findings, a majority of patients whose electronystagmography findings indicated central and mixed causes, or peripheral lesions other than benign paroxysmal positional vertigo, had abnormal findings on posturography. Specifically, tests similar to the Balance Master Sensory Organization Tests 4 and 5 and a new test, Limits of Stability, presented the most difficulty for these individuals. Patients with normal electronystagmography findings and those with benign paroxysmal positional vertigo had mixed results on posturography. The results for specific individual electronystagmography tests were compared with those of posturography tests. No correlation was noted among any of the electronystagmography results and posturography findings. Furthermore, no correlation was observed between posturography and the causes of dizziness. CONCLUSION: For many patients with dizziness and/or balance dysfunctions, posturography can provide additional information to that obtained with electronystagmography. This is especially apparent in individuals who have these symptoms but have normal or borderline normal electronystagmography findings.
